FOOT- REST.

SPECIFICATION forming part of Letters Patent No. 360,487, dated April 5, 1887.

Application filed September 4, 1886. Serial No.2l2,720.

To all whom it may concern:

Be it known that I, LEVI STUCK, a citizen of the United States, residing at Hart, in the county of Oceana and State of Michigan, have 5 invented new and useful Improvements in Foot Stools or Rests, of which the following is a specification.

My invention relates to footstools or footrests for dental or barbers chairs, Ste. 5 and the i object of my invention is to produce a footrest which shall be simple, durable, and easily adjusted.

To the above purpose my invention consists in certain peculiar and novel features of con- I struction and arrangementof parts, as hereinafter described and claimed.

In order that my invention may be fully understood,I will proceed to describe it with reference to the accompanying drawings, in

i which- Figure 1 is a side elevation of a dental chair with my improved foot-stool applied thereto. Fig. 2 is a frontelcvation of the same, showing the improvement in dotted lines. Figs. 3 and 4 are detached views illustrating the foot-rest mechanism. p

In the said drawings, A designates the chairbottom, and B the chair-back, of an ordinary dental chair.

O G designate two brackets, bifurcated at their upper ends to form two arms, 0 0*, the front arm, C, being secured to the under side of the chair-bottom near the front end, while the rear arm, 0*, is secured near the rear end of the chair-bottom. These brackets extend forward and downward from opposite under sides of the chair-bottom, causing the lower end of the brackets to come about on a line vertically with the front end of the bottom.

0 An elongated slot, d, extends upward from the lower end of said bracket nearly to the junction of the arms 0 C.

D designates the foot-rest, which is shown as being rectangular in form and provided at its inner end with a cross-bar, d The inner ends of the side bars of the foot-rest frame are formed with upwardly-inclined extensions or cranks d", which extend beyond the cross (No model.)

bar d, and carry rollers d on the upper ends at the outer sides, said rollers working upon the rear flanged edge, 7, of the slots (1 in the brackets 0. At the angle of union between the side pieces and cranks cl of the foot-rest, which is the crossbar (P, are placed rollers (1 which are mounted on the extended ends of said cross-bar d, and work in the slots (1 of the brackets G. The relative location and action of the rollers d d is such that the foot-rest will just about sustain itself at any point within its limits of movement upon brackets 0, whether weighted or not. The rollers d form what might be termed the pivot for the foot-rest, while the rollers d, being on the cranks (2 come in contact with the brackets O at the flanged cdgef, and hold the foot-rest, so as to take the strain off the operating mechanism.

E designates a U shaped rockarm for raising and lowering the foot-rest. The cranked ends of this arm are pivoted in lugs c on bracket C, and the lower horizontal portion of said arm is connected by a pair of looselyhung links, F, to the inner crossbar, cl, of the foot-rest. One end of the rock-arm E has an extension-lever, G, which connects with one 7 5 of the cranked ends and projects rearward beneath the chair-bottom. This lever is formed at its outerend with an enlargement, g, for the operators foot, and at an intermediate point with an inwardly-extending pin, 9', for a pur- 8o pose to be presently described.

H designates a curved detent-arm, which extends downward and forward from the rear portion of the chair-bottom, and is pivoted at its upper end thereto. A slot, It, extends 8 5 nearly throughout the length of this arm, terminating at the lower end thereof, and the front margin or edge of said slot is formed with notches or rack-teeth h, which are engaged by the ping oflevcr Gr, just referred to, thus hold- 0 ing said lever at any desired point of adjustment.

The operation of the abovedescribed mechanism is as follows: In raising the foot-rest the operator places his foot upon the enlarge- 5 ment 1 of lever G, and with the toe presses against pivoted detent-arm H, moving it for ward, so that its notches or teeth h shall disengage the pin 9 of the lever. pressing upon the lever G its outer end is depressed, raising the horizontal part of rockarmEthrough the links F, and raising the footrest D to any desired extent. The tee is now removed from detent-arm H, allowing it to swing backward and engage pin g/ oflever G in one ofits notches h, and thus holding the lever against displacement. In lowering the footrest the operation is practically the same, excepting that the outer end oflever G is moved upwardinstead of downward. Butlittlestrain comes upon lever G and its connections, because, as previously stated, the relative positions of the rollers d" d is such as to render the foot-rest practically self-sustaining upon the brackets 0, whether said foot-rest be weighted or not. Consequently but little strain comes upon the operative connections of lever G, even when the foot-rest is being raised or lowered, and the entire mechanism is thus rendered very durable. The foot-rest may be turned up against the body of the chair when not in use, in order to economize space, as shown in dotted lines, Fig. 1.

It will be observed that the cranks or cranked extensions d extend from the foot-rest to a point in rear of a vertical line drawn through the pivot, and also above a horizontal line drawn through the same point, when the parts are in their proper position for use. This arrangement contributes materially to the holding or sustaining of the foot-rest in a horizontal position for use, so as to take the weight and strain ,off the adjusting and elevating means.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combinationwith suitablebrackets depending from the chair body or frame, a footrest frame provided with rollers which bear against opposing faces of the brackets, and the elevating and adjusting means for the foot-rest frame, said rollers coming in contact with the brackets when the foot-rest frameis in position,

7 whereby the weight and strain of the foot-rest frame is taken off the elevating and adjusting means and applied to the brackets,,as set forth.

2. The combination, with suitable guidebrackets, 0, depending downward from the chair-body, of a foot-rest frame, D, supported adj ustably upon said brackets, a rocking arm, E, connected to said foot-rest frame, and an extension-lever, G, upon said rock-arm for operating the latter, substantially as described;

3. The combination, with suitable guidebrackets, 0, depending from the chair-body, and a foot-rest frame, D, supported adjustaably upon said brackets, of a rock-arm, E, having suitable connections with the foot-rest frame, an operating-lever, G, for the rock-arm, and a swinging detent to engage and hold the operating'lever, substantially as specified.
